An IP address lookup that's honest about location
Enter any IP address and this tool shows you who operates it and roughly where it sits: the ISP or hosting company, the autonomous system number (ASN) that identifies the network, an approximate location, and the reverse-DNS hostname the IP points to. You can also enter a domain — we'll resolve it to its server's IP first, then run the same lookup, which is handy for finding out where a website is actually hosted.
Why the location is "approximate"
This is the part most IP checkers quietly overstate. IP geolocation is an estimate, not a GPS fix. The data maps an IP to a likely city or region based on where the network is registered and observed, but it can be off by hundreds of miles, often reflects the ISP's location rather than the actual user, and is essentially meaningless for VPNs, proxies, and cloud servers that can route from anywhere. So we label the location as approximate and ISP-level, and we treat the ISP and ASN — which are reliable — as the trustworthy part of the report. If you need to know who runs an IP, that's solid; if you're trying to pin down a precise physical address, no IP lookup can honestly give you that.
ISP, ASN, and hosting type
The most dependable fields are the network ones. The ISP or organization tells you who's responsible for the IP — a consumer broadband provider, a mobile carrier, or a hosting company like a data center. The ASN is the unique number identifying that network on the internet, useful for spotting that several IPs belong to the same operator. When an IP belongs to a data center or is flagged as an anonymizing proxy or VPN, that's worth knowing — a connection from a commercial data center IP means something different from one on residential broadband, which is why fraud and security teams pay attention to this distinction.
Reverse DNS on the same screen
We also show the reverse-DNS (PTR) hostname the IP resolves to, and whether it's forward-confirmed — the round trip that mail servers rely on. For a deeper reverse-DNS check, the dedicated reverse DNS lookup shows the full forward-confirmation detail. And if you came here from a domain, the full domain lookup ties the IP back to the registration, nameservers, and certificate picture.
